Demand paging remains useful for managing memory even when the available physical memory exceeds your virtual memory needs: you needn't wait for a large program to load in its entirety before you can start using part of it (a particular boon if the input data is such that most of the program never gets used). Similarly, the ability to run multiple programs per processor may remain useful even when processors are plentiful, if it lets you run several unimportant tasks on one CPU so that a very important task can use all the other CPUs. -- ...decwrl!mips!sjc Steve Correll
